On the eve of the 2025 Macau Financial Summit, an unsolved robbery case doubled the pressure on the police, and they had to rehire Huang Dezhong, an old detective who had an old grudge with the young policewoman He Qiuguo.
Their opponent is a family-style criminal gang headed by retired international soldier "Shadow" Fu Longsheng. His six sons and one daughter each have their own unique skills and are hiding in an orphanage. They are planning to commit bigger crimes during the summit.
During the investigation, Huang Dezhong's traditional case-handling methods were incompatible with the police's mainstream AI technology, and the key to the case unexpectedly fell on an online chat with his youngest daughter Lin Xi - the hacker Xitai she met turned out to be triplets who had been separated for many years from the team's core Xiwang and Ximeng.
Ximeng's discovery creates the first rift in this secretive family, and Huang Dezhong must resolve the knot with He Qiuguo in the countdown to the summit, combine old and new investigative methods, and prevent a crisis sweeping the city when these shadows gather in Macau.
